on New Yonai, N. Y., n CORPORATION oF DELA- Application filed January 27, 1922. lt'eriaI No. 532,152;

This invention relates'to hoists 'designed for use in the freight handling systems especially adapt-ed for use in freight stations and its principal vobject is to facilitate' the transfer of freight from one freight station to another. These systems ordinarily have a series of trucks with removable boXI bodies',-

said bodies being taken off the truck by'a hoist and deposited by the' hoist inthe de'- sired position in the freight house where it is loaded and then placed'upon the truck by the hoist. For the efiicient operation of such systems it is necessary for all freight stations inthe city to be equipped with the syst-em. Then a truck will bring a kload of freight from one freight station to the other where it is taken off the truck and another loaded body is placed thereon to be returned yto the first freight station. In this way the trucks do not have to wait for the loading` andunloading, and alsothe body can be taken to the Vfreight itself instead of Wheeling yand carrying the freight to the body.

This system has been installed in Avarious places and is proving very satisfactory.

As stated above, this invention is animproved hoist or crane for removing from or placing on said trucks thebodies oi' boxes in which the freight is loaded; In order to do this satisfactorily the hoist must be so designed that it will notonly lift the bodies and carry them from place to place, but it also must be so designed that the body can be rotated through a' few degrees so that it'can be placed in the correct position upon `the truck without any trouble. As will be read'- ily seen, if the hoist or crane were not capable of giving the body a slight rotation the truck upon which it is to be deposited would have to vbe parked directly under the hoist and eXact-ly parallel to the sidesof the body carried by the hoist. can rotate the body a few' degrees no particular care need be taken in positioning the In the drawingsFigyl is a top plan view of the apparatus; Figs, 2, 3 and 4 are sections on the lines 2;-2, 3 3 and respectively, of Fig. 1, and Fig. 5 isa section on the line 5-5 of'Figg2.

Two spaced lrails 1 and'2 upon whichv the hoist or cra-ne rides (which rails vmay be built up the channel irons and plates as shown or may be ordinary I-beam) are suspended direction of 'rotation of the shaft'f20. However, if .the 4hoist from the ceiling of rthe building. The'vhoistor crane comprises two pairs ofchannel irons 3 and 4 Vand 5 and 6, the channel irons 3 and 4be-ing Vplacedon vopposite sides 4of the rail 1 and connected across the' bottom bycross. pieces 7,' and the channels 5 and '6` being vplaced on opposite sides ofthe rail 2 and connected across the bottom by cross pieces 8. The channel irons 4 and 5 are connected together by cross beams 9, 10, 11 and 12.l

The channel' irons 3', 4, 5 and A6 have ate.

tached thereto studs 13 and 14, the studs 13 having rotatably mounted -thereon track vwheels 15,'which ride on the iianges ofthe rails 1 and 2, and roller or ball bearings 16 between the rear faces ofthe track wheels 15 and the channelirons 3, 4, Sand 6. i IThe studs 14 have rotatably mounted thereon track wheels 17 to which are rigidlyattached gears 18. Roller bearings 19 similar to the bearings 16 are placed 'betweenthe gears 18. and the channel irons 3, 4, '5 and 6. V

lA shaft 20, carried in bearings" 21 at# tached tothe lower flanges of thechannel irons 3,4, 5 and 6, has gears "22' thereon which mesh with the gears 18. Onelend of the shaft 21 has mounted thereon a wheel 23 which carries an endless chain'or-'cable'24 by which the shaft 2O is rotated by a person'on the'floor. It is to be understood that .if so desired the wheel v23 and cable or chain 24 maybe placed on either or both ends of the shaft 20 as desired; also the shaft r20 may be rotated byv a motor carried by the frame, if it is desired to do so. By rotating the shaft 20 the gears 22 and 18' and consequently the track wheels 17 'are rotatedvwhichwill cause the frame carried -by vthe wheels 15 and' 17 to be moved along the tracks 1 and 2, vthe direction of the movement d ependingup'on the A shaft 25 is carriedr in'brackets26 depending from the lower flanges of the channels 3, 4, 5 and 6 midwayfbet-ween the studs 13 and 14. Drums Y27 are `vsecured to A'the shaft^25 near the'ends thereof beneath lthe rails 1 and 2. The shaft '25 is rotated-'by a motor 28 (carried on cross beams 29vextending between the beamsy 11 and 1 2) 4through gears30 and 31 and a worm gear reduction carried ina housing 32 ksuspended from 'the cross bars' 10 and `1l.l 33 indicates'shaft couplings.

` Four "frames, A'generally denoted by* 3 4 vertical end members 36 an 6. As is clearly shownin the drawings, the

which consist of horizontal to jinembers 35, intermediate members 37, parallel to the end members 36 and lower horizontal connecting members 38 whichv connectthe'lower ends of y.the inem-V ber's 36 and 37, are slidably mounted upon `the roller bea- rings 16 and 19 between the wheels and 17 and the channels 3, 4, 5 and lower members 38 of the fra-mes 34 are con c nectedV by shafts l39 and40, the shafts B9 carrying sheaves41 and thel shafts 40 carryingsheaves 42. As will be seen'bythe drawings thesheaves 41: are yin alignment with each other, and the sheaves 42 are in alignment with each other. Y `cross ieces 7 and 8 are eyes 43Y to which one Depending from the end-o cables 44 is secured, theother ends of said cables being secured to the vdrum 27 and Wound thereon in opposite directions as islshown fclearly in Fig.r The cables 44 run fromfthe drum 27 and over the sheavesv 42;,- thence f downwardly. and around the sheave wheels 45 which carry sheave blocks 46 and thence upwardly and over the `sheaves 41 jand thence to the eyes 43 vwhere they are v34 mounted between the tracks 1 andv 2. As

will be Vnoted in Fig. 2, thefrack 50 is below the gear 49 while the rack 502L is above the gear 49". The shaft 47 is rotated by a wheel 51 and endless chain orcable'52, said wheel 1 and chain being similar to the wheel and chain 23 and 24 respectively. l/Vhen the shaft 47 is rotated, the opposing pairsof frames 34 will be lcaused to move in opposite direc- 45 tions by the gears 49 and 49 and racks 50 1Q and 50a. The frames '34v will move easily,

due to the fact that they are mounted on the roller bearings 16 and 19.. VThe shifting of the framesl 34 will not affect the height of the sheaveblocks 46 as the distances between the fixed ends of the cables are always constantv no matter what positions the frames are in. c

AIn operation the device is used as follows: The hoist or crane is brought over the box or body to be moved, (said bodybeing indicated ,in dot and dash lines in Figs. 2 and) by rotating-the shaft 20, gears 22 and 18 and conse uently the track wheels 17. Then it is broug t, overvr the body, the shaftV 25 and consequently the drums 27 are rot-ated by the motor 28 and interposed gearing which allows the four sheave blocks 46 to be lowered until they are fastened to hooks carried by the body or box. Then the shaft 25 is roftated in the opposite direction which raises it from the truck or floor as tliecase Amay be and it is carried to the place desired.

lowering the box, if any angular movement is" desired, this is secured'by rotatingy the shaft 47 which' will move'the frames llidi-and consequently the sheave blocks 46 Vin opposite directions which will give a slight angular movement .to the box or body carried by the blocks 46.

' It will be' seen that,bytheineansdescribed I have provided for shiftingthehoisting cables longitudinally with respect 'tol fthe maintrack of the crane, the cables atkoppoi site sides being Vshifted Vin oppositekrdirections, so that'a box or load suspended by the cables will be sl ewed,'iiioi'e or lesswith respect to the line of travel ofthe crane and y will thereby be disposed in an angular posi-l tion so that` it may be lowered inproper position on a` truck, even if the latter is not'.

located in a position exactly parallel to. theV travel of the crane. This resultis particularly desirable in installations .of this kvind where the` load is suspendedat four points. A load suspended from a single point can of course be quite readily turned- `by hand, but this would be attendedwithsome didiculty in a crane of the present type.
